Mutsari: Muhleri wa sayiti Ku kandziyisa nkarhi: 2024-08-15 Masungulo: Ndhawu
Loko sisiteme ya gezi yi ri karhi yi hluvuka, mpimo wa giridi wu ya emahlweni wu kula, leswi yisaka eka swilaveko swa le henhla swa vuhlanganisi bya gezi. Tibetiri, tanihi xiphemu xa nkoka xa sisiteme ya gezi ra thelekhomu, ti na nkucetelo wo kongoma eka ku tshembheka ka vuhlanganisi bya gezi. Ku endla ku kamberiwa ka vuswikoti hi ku tirhisa swirhendzevutani swa ku chaja na ku humesa i ndlela ya nkoka yo hlayisa matirhelo ya betri na ku engetela vutomi bya betri. Hi ku ya hi milawu ya vuhlayiseki bya fambiselo ra gezi ra thelekhomu, tibetiri ti lava ku hlayisiwa nkarhi na nkarhi. Loko ku pimanisiwa na tindlela to fana na ku pima voltage ya le makumu na ku kamberiwa ka ku lwisana ka le ndzeni, ku kamberiwa ka vuswikoti swi nyika ku pakanisa lokukulu. Tibetiri letintshwa leti nghenisiweke ti lava ku kamberiwa ka ku humesiwa ka swilo hinkwaswo, ku landzela ku kamberiwa ka ku humesiwa ka vuswikoti bya lembe na lembe. Eka tibetiri leti tirhaka ku ringana malembe ya mune, ku kamberiwa ka vuswikoti bya le xikarhi ka lembe na lembe swa laveka. Loko betri yi tsandzeka ku fikelela 80% wa vuswikoti bya yona lebyi ringanyetiweke endzhaku ka swikambelo swinharhu hi ku landzelelana, yi fanele ku tekeriwa enhlokweni ku cinciwa.
Sweswi, swikimi swinharhu leswi tolovelekeke swa ku kamberiwa ka vuswikoti bya betri swi tirhisiwa ngopfu eka vunjhiniyara: ndzhwalo wa dummy, ku hundzuriwa ka DC/AC, na swikimi swa voltage ya DC/DC boosted.
Xitirhisiwa xo kambela vuswikoti ngopfungopfu xi na modyuli ya xirhendzevutani leyi tlakusiweke ya betri ya DC/DC ya frequency ya le henhla, modyuli ya xiyenge xa le henhla ya frequency ya DC/DC ya betri ya nkarhi hinkwawo ya ku chaja, swihlanganisi, na ti-diode. Endlelo ri tirha hi swiyimo swinharhu: ku yima ku papamala chaji, ku humesiwa ka vuswikoti, na chaji ya current leyi nga cinciki. Mimfumo leyi yi vumba xirhendzevutani xa ntirho lexi heleleke xa ku kamberiwa ka vuswikoti.
Standby Floating Charge State .
Eka xiyimo xa charge lexi papamalaka, NC contactor K1 yi pfariwile, naswona no contactor KM ya pfuleka. Betiri yi le ka inthanete, laha rectifier yi phakelaka matimba eka betri na ndzhwalo. Loko ku ri na ku yimisiwa ka gezi loku nga languteriwangiki, betri yi nga nyika gezi hi ku kongoma eka ndzhwalo, ku tiyisisa mphakelo wa gezi lowu nga kavanyetiwiki.
Xifaniso 1: Xipaci xa betri lexi nga eka xiyimo xo yima xa ku papamala .
Xiyimo xa ku humesiwa ka vuswikoti .
Hi nkarhi wa ku humesiwa ka vuswikoti, xihlanganisi xa NC xa K1 xa pfuleka, naswona vahlanganisi va No Contactors KM na KC va pfala. Xirhendzevutani xa Battery Pack lexi tlakusiweke xa frequency ya le henhla xa DC/DC xa tirha. Betiri yi tlakusiwa hi xirhendzevutani xa DC/DC kuya eka voltage yale henhla nyana kutlula voltage ya rectifier, xisweswo yi siva rectifier eka ku phakela matimba eka ndzhwalo. Loko ku hetiwa ku humesiwa, sisiteme yi cincela hi yoxe eka ku chaja ka current ya nkarhi hinkwawo, laha modyuli ya xirhendzevutani xa charge ya nkarhi hinkwawo yi tirhaka.
Xifaniso xa 2: Xipaci xa betri eka xiyimo xa ku humesiwa ka vuswikoti .
Xiyimo xa chaji ya nkarhi hinkwawo ya sweswi .
Endzhaku ka ku humesiwa ka vuswikoti, sisiteme yi cincela hi yoxe eka ku chaja ka current ya nkarhi hinkwawo. Modyuli ya xirhendzevutani xa charge circuit ya charge ya nkarhi hinkwawo ya frequency ya DC/DC ya frequency ya le henhla ya tirha, hi ku tisungulela yi lulamisa current ya charge eka nhlayo ya set loko yi ri karhi yi tirhisa rectifier ya xiviri eka ku chaja ka current ya nkarhi hinkwawo. Loko voltage ya betri yi ya yi kula eku heleni ka endlelo ro chaja, current yo chaja ya hunguteka. Loko current yi wela ehansi ka set threshold ya xitirhisiwa, sisiteme yi tiendlele ku herisa constant current charge process. Muhlanganisi wa NC K1 u pfala, a yimisa modyuli ya xiyimo xa le henhla ya DC/DC ya betri ya nkarhi hinkwawo ya ku chaja ka current, na ku tsema KM na KC. Kutani battery pack yi tlhelela eka xiyimo xa standby floating charge.
Xifaniso xa 3: Xipaci xa betri eka xiyimo xa ku chaja ka nkarhi hinkwawo xa current .
Leswi nga laha henhla swi hlamusela ku tirhisiwa ka sisiteme yo kambela vuswikoti leyi simekiweke eka DC/DC. Ntlhantlho wu amukeriwa ngopfu hi vaendli va indasitiri. Hi xikombiso, DFUN yi endle xitshunxo lexi heleleke xa le kule xa ku kamberiwa ka vuswikoti bya inthanete, ku fikelela vulawuri bya le xikarhi bya tindhawu leti hangalakeke hi le kule, leswi hlayisaka nkarhi, leswi olovaka, naswona swi tshembekaka.
DFUN Capacity Testing Solution , ku engetela eka ntirho wo kambela vuswikoti, yi katsa ku langutisisa betri hi nkarhi wa xiviri na swihlawulekisi swa ku tirhisa betri, ku endla leswaku ku va na vulawuri bya le kule, ku tshama nkarhi wo leha na ku hlayisa tibetiri.
